Hello Blumbly & Bigted.
First Blumbly I was thinking you must have either forgot to take you medication or taken too much, as I used two Mustangs in a mowing business in the 70's, but don't remember all the details.... Your probably right as the guy put this machine together with any parts on hand then sold it.
Now bigted, there is a good spark, a new chinese plug from cheap shop. I put the correct jet in for a 160cc engine not a 125 that was in it, and I put a black needle in.
It's got a white poppet valve with ABC in, but I remember my old Mustangs had a black poppet valve as I used to clean the carbs every week......
I left the white one in.
I dump the kill wires, fill the space with hotglue.
I put a new started cord in.
Anyway i started ok, mowed the front yard, let it sit for 15 min, and restarted ok. then started it later in the afternoon, it started again, so I'm thinking it will be ok. I want to keep this one for myself. I'll sell my good 4 stroke my mate gave me instead.

thanks
speedy
Bundy
